- Video stride analysis on how elite runners utilize a strong vertical hip strategy:
• powerful upward hip flexion
• powerful, fast, foot-to-ground hip extension
to generate long, powerful strides, a fast cadence, and an efficient foot-under-body landing
Similtaneous:
Hip flexor driving upward extending glut,
Pushoff driving upward and extending other hip flexor,
Opposite arm driving upward extending shoulder..
Then all extended body parts spring into flexion simultaneously, and all flexed Opposite body parts begin to spring and drive into extension.
Alternating vectored plyometric jumps, facilitating and being facilitated by the opposite side
Love the video. PS: It would be nice to credit the original videos
Great video, Joe! I’m curious of what you would say about a guy like Jacob Ingebretson or other faster track guys who have the foot casted out at the landing and look like they pull the body more over the foot and it’s more “front side action”? Thanks for the great breakdown
That "pull" is what actually makes it a "backside" strategy. In the same way pulling a bow backward seems "back", that's the energy the propels the arrow forward. As such: the "flicking" ("casted out") is the wind-up for a strong rearward pull-push force.
Love these videos but it would be great to hear all this without any jargon as explained to a towel newb. Flexing and driving are abstract concepts so as a beginner I’m not 100 percent sure what those things actually mean in practice if that makes sense.
I have noticed the potential overreach as well, and then at the last second they reduce the stride leagnth, my assumption is that by starting the pull portion before you touch the ground your matching your speed otherwise your forced to increase your pull from a dead stop in order to continue your momentum/speed which I assume uses more energy as requires a faster zero to 60 speed which translates more inefficient then over striding and starting the pull in the air.
Good point about the circularity of the stride. Tho don't really see Wamsley (or Jornet) placing their foot down "beneath" them. It's certainly not under their hips, but yes it's not really reaching. The tibia is generally 90 deg to the ground but many cms forward of his trunk.
The vertical shin is key. But again we over-rely on what we 'see" (the kinematics). It's the KINETICS - the force production - that turns an angled shin, vertical and creates a pull-push propulsive effect beneath and behind.
Can you cite any scientific data that backs up your claims about "vertical" forms being more efficient than the "horizontal" forms?
Yes, force plate data from using force-plate treadmill analysis on 100s of PT clients. Horizontal = over-stride landing.
Consider doing a google scholar search of "shin angle" (metric of vertical vs horizontal strategy) and ground reaction forces, injury incidence.
